2.7.3 Changing The Lens
The M24M can be shipped from the factory with five MOBOTIX standard lenses (L22,
32, 43, 65, 135) with the CSVario lens or the hemispheric L11 lens. This procedure applies
equally for all lenses. However, the removal/installation of the lock ring is not required for
the M24M-Sec-CSVario nor for lenses with CS or C mounts.
Only lenses with CS or C mounts may be used with the CSVario version of the M24M
(Secure model only). Only standard MOBOTIX lenses (L22, 32, 43, 65, 135) with M14 thread
may be used with standard versions of the M24M (Secure, IT and Basic). With the M24M
180° hemispheric camera, only the hemispheric L11 lens may be used. Upgrading to other
model versions is not possible.
Proceed as follows to change the lens:
1. Remove the lens cover by turning it counterclockwise.
2. Loosen the lock ring of the lens by turning it coun-
terclockwise.
3. Remove the lens with the lock ring by turning it coun-
terclockwise.
4. Unscrew the lock ring from the lens you just removed
and screw it onto the new lens.
5. Screw the new lens with the attached lock ring back
into the camera.
6. Adjust the image sharpness according to the camera's
live image on the computer monitor. To avoid damaging
the lens mount, never turn the lens too far or with force.
7. Tighten the lock ring by turning it in a clockwise
direction to secure the lens.
8. Screw the lens cover onto the lens again and clean it,
if required, using a clean, lint-free cotton cloth.
The focusing aid provides a visual aid when setting the image
sharpness of a MOBOTIX camera lens (see Section 4.3.3 Image
and Audio Settings, Quick Controls in the Software Manual).
